The purpose of this study is to evaluate efficacy of erdafitinib versus chemotherapy or pembrolizumab in participants with advanced urothelial cancer harboring selected fibroblast growth factor receptor (FGFR) aberrations who have progressed after 1 or 2 prior treatments, at least 1 of which includes an anti-programmed death ligand 1(PD-\[L\]1) agent (cohort 1) or 1 prior treatment not containing an anti-PD-(L) 1 agent (cohort 2).
A study of erdafitinib versus standard of care, consisting of chemotherapy (docetaxel or vinflunine) or anti-PD-(L) 1 agent pembrolizumab, in participants with advanced urothelial cancer and selected FGFR aberrations who have progressed on or after 1 or 2 prior treatments, at least 1 of which includes an anti-PD-(L) 1 agent (cohort 1) or 1 prior treatment not containing an anti-PD-(L) 1 agent (cohort 2). It will consist of screening, treatment phase (from randomization until disease progression, intolerable toxicity, withdrawal of consent or decision by investigator to discontinue treatment, post-treatment follow-up (from end-of-treatment to participants death, withdraws consent, lost to follow-up study completion for the respective cohort, whichever comes first). The study will have long term extension (LTE) period after clinical cutoff date is achieved for final analysis of each cohort and participants eligible in the opinion of the investigator, will continue to benefit from the study intervention. Efficacy, pharmacokinetics, biomarkers, patient reported outcomes, medical resource utilization and safety will be assessed.

Overall Survival (OS)
Overall survival was measured from the date of randomization to the date of the participant's death.
Time frame: From randomization (3 days prior to Cycle 1 Day 1) until death due to any cause (maximum up to 51.7 months)
Progression Free Survival (PFS) as Per Response Evaluation Criteria in Solid Tumors (RECIST) Version (v) 1.1
PFS was defined as the time from the date of randomization to the date of disease progression or relapse from complete response (CR) based on investigator assessment using RECIST v 1.1, or death due to any cause, whichever occurred first. As per RECIST v 1.1, CR was defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must had reduction in the short axis to less than (\<) 10 millimeters (mm). Progressive disease (PD) was defined as at least 20 percent (%) increase in the sum of diameters of measured lesions taking as references the smallest sum of diameters recorded on study (including baseline) and an absolute increase of greater than or equal to (\>=) 5 mm or appearance of at least 1 new lesion.
Time frame: From randomization (3 days prior to Cycle 1 Day 1) until disease progression or relapse from CR or death (maximum up to 51.7 months)
Objective Response Rate (ORR) Per RECIST Version 1.1
ORR was defined as the percentage of participants who achieved CR or partial response (PR) as determined by investigator per RECIST v1.1. CR was defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must had reduction in the short axis to \<10 mm. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.
Time frame: From start of the treatment (Day 1 Cycle 1) up to maximum of 51.7 months

The response options ranged from 0 to 4 where, 0='Not at all" and 4= "very much." FACT-Bl total score ranged from 0 (worst) to 156 (best). The higher the score, the better the quality of life (QOL). The baseline value was defined as the value collected at the time closest to but prior to the randomization.
Time frame: Baseline up to Cycle 11 (each cycle was of 21 days)
Time Until Symptom Deterioration
Time until symptom deterioration was defined as the first time to increase in urinary bladder cancer symptoms score from the day of randomization beyond a meaningful change threshold compared to baseline.

Response options ranged from 0 to 4, 0 = Not at all, 1= A little bit, 2= Somewhat, 3=Quite a bit, 4 = Very much. A response of 0 indicated no symptoms and 4 indicated severe symptoms. Total sum scores ranged from 0 to 12, higher scores indicate relatively poor quality of life.
Time frame: Randomization (3 days prior to Cycle 1 Day 1) up to maximum of 51.7 months
Percentage of Participants With Shift From Baseline in Patient-Global Impression of Severity (PGIS)

Percentage of participants with shift from baseline in PGIS score were reported. A negative shift from baseline in PGIS score indicated Improvement and positive shift from baseline in PGIS score indicated Worsening. The baseline value was defined as the value collected at the time closest to but prior to the randomization.
Time frame: Baseline, 51.7 months

Health utility values generated from the EQ-5D generally range from 0 (a state as bad as being dead) to 1 (full health), with higher scores indicating better QoL. The EQ visual analog scale (VAS) recorded the patient's self-rated health on a VAS, ranged from 0 (worst imaginable health state) to 100 (best imaginable health state), with higher scores indicating better QoL. The baseline value was defined as the value collected at the time closest to but prior to the randomization.
